Adaptive Headlight Sweep for Vehicle Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles with a single functional headlight can be misidentified by other drivers as a motorcycle or bicycle, leading to potential safety hazards due to confusion about the vehicle's size and type.
Innovation Solution
Adaptive headlights that produce a continuous beam sweeping effect by either cycling through multiple beam profiles or physically rotating the headlights, which are controlled by a processor to detect headlight failure and adjust the beam pattern to simulate a swiveling motion, thereby distinguishing the vehicle as a sedan or SUV.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle has only a single functional headlight, then the vehicle can still provide basic illumination, but other drivers may misidentify the vehicle as a motorcycle or bicycle, creating safety hazards
Solution Approach 1:
The system implements periodic action by cycling the single functional headlight through multiple beam profiles at different angles and positions. The processor controls the headlight to sweep across various directions in a repeating pattern, creating a dynamic light pattern that mimics the appearance of multiple headlights working in unison. This periodic sweeping action communicates vehicle size and type to other drivers while maintaining basic illumination functionality.
2Loss of information
If the headlight produces a continuous beam sweeping effect by cycling through multiple beam profiles, then the vehicle can effectively communicate its size and type to other drivers, but the system complexity increases due to the need for processor control and multiple beam profile management
Solution Approach 1:
The system applies universality by using a single headlight unit to perform multiple functions: it provides basic illumination, communicates vehicle identification information, and creates the sweeping beam effect. The processor manages multiple beam profiles within the same headlight assembly, allowing one component to fulfill several roles that would traditionally require multiple separate systems.
3Object-affected harmful factors
If the headlight continuously sweeps through multiple beam profiles to simulate a swiveling motion, then the vehicle can alert oncoming traffic and disperse animals, but the energy consumption increases compared to a static headlight beam
Solution Approach 1:
The system uses periodic action to cycle through beam profiles in a controlled manner, creating the sweeping effect only when necessary for communication purposes. The processor manages the timing and sequence of beam profile transitions, allowing the headlight to return to lower-energy positions between sweeps, thereby balancing animal dispersion effectiveness with energy conservation.

AI summary
A vehicle includes: adaptive headlights, each configured to produce a continuous beam sweeping effect, processor(s) configured to: (a) detect failure of an adaptive headlight; (b) control the functional adaptive headlight to produce the continuous beam sweeping effect based on (a). The functional adaptive headlight achieves the continuous beam sweeping effect by (1) continuously cycling through a plurality of beam profiles, or (2) continuously rotating the headlights via motor(s).
